The module is called __private out of a reason ;)

It saves the caller from having to manually do the Decode::decode. I can remove it if you want, but I think it's useful.

When using the relay chain though a
Arc<dyn RelayChainInterface>there is no way to call arbitrary runtime apis. Both implementations of that trait allow this, so it feels natural to expose this functionality in the trait.This PR adds a
call_runtime_apimethod to RelayChainInterface trait, and a separate function also namedcall_runtime_apiwhich allows the caller to specify the input and output types, as opposed to having to encode them. This generic function cannot be part of the trait because adyn Traitobject cannot have generic methods.
